yea a prelube tank is nice,if ya got air,,iuse one at work,,,sometimes a tank is an easy thing to set up so heres what i did,,,,take an old vacuumpump,,and lookwhere the gear engages with the oil pump,pull out that seal,,,then do what you gotta do to remove the shaft with the drive gear from the pump,soyou end upwith the shaft and gear not in the pump bodyi actually used a sawzall to cut the thing in half,right below the main pump part ,i used an a2 vane pump, for the destruction:twisted: ,,,now grind all the teeth off the gear,clean it up,,,look close theres an oilhole in the shaft,,,,,,iwelded a 1/2 inct nut on the top,,doing 2 things filling the hole,and giving me a hex to drive the shaft with a drill,,,,hell its so easy i now use it on oilchanges,,i dont even bother to fill the filters when i use this,,spin it up to pressure and hold it for a minute or so,,just gotta remove the vacuum pump,,on mycar thats easy,,,, throw the orig. pump backin and fire it up!!!!
